甲醇与氢硼化物反应十分快,乙醇稍慢,但是异丙醇和 t-丁醇反应儿可忽视,所以这些溶剂可作为氢化硼钠与丙酮的动力学研究的介质。氢化硼钠和丙酮在水、乙醇、异丙醇中的反应速率在动力学上表现为一级,这个作用物如为一级,在水中加入氯化锂对速率无影响,但在异丙醇中速率增加三倍,这表明在水中包 The reaction between methanol and borohydride is very fast and the ethanol is slightly slower. However, the reaction between isopropanol and t-butanol can be neglected. Therefore, these solvents can be used as the mediator for the kinetic study of sodium borohydride and acetone. The reaction rate between sodium borohydride and acetone in water, ethanol, and isopropanol is kinetically one order. The effect of this reagent, such as first order, on the rate of addition of lithium chloride in water has no effect on the rate, The medium rate increased threefold, indicating that the package in water
